' u Application filed December 13, 1880. No model.)

To all whoin it may concern:

Be it known that I, WILLIS J. PERKINS, of

Grand Rapids, in the county of Itasca-and State of Michigan, have invented certain new, and.

useful Improvements in Shingle-JointingMachines; and I do hereby declare the following to be a full,'clear, and exact description ofthe invention, such' as will enable others skilled in the art towhich it pertains to make and use it, reference being had to the accompanying drawings, which form part of thisspecification. y'invention relatesito an improvement in shingle-jointin g machines." V

The object a of machines of the byhdaptingithni to be laid closely together andinstraight rows on a roof.

My improvement in ."shingle-jointing ma chines relates to that clas's of Inachines'w'hich' employ a revolving disk or;wheel provided 1 withknives orcutters against which theshinr-gle to be jointed is held while the jointingw-heelyis revolving. The mainobjectsofmy invention, then, are, first, tofprovide a shingle-jointing machine with a shield adapted to be raised to expose one-half of the cutting-wheel, andv thus facili tate' the sharpening and adjustment'of lthe knives second, to adaptashingle-machine, by providingone tacetoffltheshield' with two ta, bles or rests, and theiopposite face thereof with on'etable and making the said shield reversible, to be used either byone or two personsin truin g shingles; and, third, to' provide adj ustm ent-for the butting-pieces on thetable onwhichTthey arem'ount'e 1 i 1 I My inventio'n furtherconsists in certain de-' tailsof construction andcombinations of parts, as will? be hereinafter described andclaimed; In'the accompanying" drawings, Figure l is aviewi in'perspective of ashingle-jointing ma chinerconstr'uctedin accordance with my inventi0n,'and presenting that face ofthe reversicharacter l rsaindicated is'totrue the edges of shingles as they come in the rouglrfrom the shingle-maperposed on the operating table or rest. Fig.

4 is a view in longitudinal vertical section of a bed on which the cutting-knives are mounted 'on the jointing-Wheel, and Fig. 5 is an enlarged view of the'adjustable socket.

LetA represent a frame supporting a semicylindrical box, B, having a flange, 0, extending around its open upper face.

. Midway the length of the flange 0, formed as above described, on each side of v the semicylindrical box B, a journal -bearing, D, is placed to receive the shaft a of the jointing- -Wheel A, said shaft being retained in position in its journal-box by a cap designated by a".

One-half of the cutting-wheel A ,at whatever I part of its revolution it may be, is always inolosed'in the stationary. box' or sheave B, that portion of the wheel extendingabovethe said box B being covered and 'protectedby a reversible hinged shield orhood, B, the several uses and functions of which will be hereinafter stated. 1 .It is to he observed that the rear portion of the flange C, which spans the periphery of the box B at each end thereof, is provided with angled plates 1), the same being in'any suitable manner secured thereto, saidplates b offering convenient points, whereby thelhood or shieldBt may be hinged, by-means'of'ears c forming a part thereof, to .thefiange O of the box or sheath B. The vertical arms at of .the an gled'plates 'b are perforated to admit abolt, a, as are alsothe ears 0 of the shield. The bolt a passing through the said vertical arms and ears, as shown inthe drawings, forms a -pi v'- otal adjustment for the shield'well'adapted to resist lateral motion,and yet one that may be easilysevered by removing the bolt, thus allowing the shield to bejreversed to present "eitherfaceithereofto the frontof the jointingwheel. The forward and rear portions of the shield being counterparts of each other, and each endbeing provided with ears, as above described, both will 'be equally well adapted to. assume a' pivotal or hinged relation with respect to the rear end of the flange G.

il'havedescrihed above one method ofadjustably pivoting the shield of a jointing-machine to the semi-cylindrical box thereof; but Itwish it to be 'distinctlyunderstood that I do not limit myself to any peculiar form'ot' pivoting device, as I may employ any one of numerous means of accomplishing this end as occasion may suggest or exigency require.

An adjustable socket is secured to that portion of the flange C which spans the forward end of the box B. The object of the adjustable socket aforesaid is to lock the shield B firmly on the flange when in a closed position, and thus efl'ectually prevent any lateral movement thereof and consequent alteration and variance in the sides of the shingle, and also to replace the shield after having opened it to adjust theknives in exactly the same position in which it was before being opened, so that theshinglesmaybeuniform. Thesocketwhich I have here shown for the purpose indicated consists in an elongated plate, D, having two lateral slots, d, by means of which latter itis adapted to be secured by bolts d to the flange G, and have lateral movement thereon. The said plateD is further provided with two vertical arms, between which one of the ears 0 of the shield is received when closed into working adjustment on the wheel-casin g. It is to be noted that this locking will be effected in either of the two positions which the shield may assume, inasmuch as one end thereof is a counterpart of the other. I would again declare that I do not limit myself to this particular form of socket, as it is evident that other devices entirely independent of the ears 0 of the shield may be attached thereto, and may have suitable sockets secured to flange C to receive them.

I have provided the rear end of flan ge G with a horn, H. This is designed to support the shield after it has been opened sufficiently far to allow the cutting or jointing wheel to be operated upon, thereby avoiding the strain on the pivotal connection between the shield and box were it allowed to fall over as far as it would without the interposition of some medium, as this horn H, to prevent it.

The front face of the shield B is provided with two tables or rests, B, so called because the shingles are rested or supported on them when presented to the cutting or truing action of the knives on the jointing-wheel A. The front face of the shield is provided with two tables, while the rear face thereof has only one.

It will be often a great advantage and saving of power to put two operators at the same machine, whereby one machine is made to perform twice the amount of work than if operated by one man unaided. In order to secure accommodation for both I provide one face of the shield with two rests, as seen in Fig. 2 of the drawings, and yet as the presence of the second table is a source of inconvenience when the machine is being operated by a single person, Ihave made the shield reversible and provided its reverse face with a single table. By reversing the shield by means hereinbefore described 1 am thus enabled to make the shield perform a twofold function. The said tables,

B are constructed in the usual manner, and are secured to the shield by means of depending flanges (1 The inner end of the tables which have a broader bearing-surface than their outer ends, are provided with two arms, b 0 upon which butting-pieces d are superposed and have pivotal movement to gage the shingle parallel and square with the butts. The inner end of the butting-piece is adapted to be pivoted to the arm I) of the rest, while the outer arm, a, thereof is provided with an elongated slot, through which a bolt, 0 passes, and by means of which the adjustment of the butting-piece d is controlled.

The jointing-wheel A, as shown in the drawings, is provided with six knives. A greater or even less number may be used if desired, but six are found to admirably fill every requirement. These knives are set at such an angle to the periphery of the wheel that, as it revolves, a draw-stroke, cuttingsmoothly, rapidly, and easily, will be imparted to them. The rear face of the jointing-wheel A is provided with knife-bearings, having a slotted plate, A, and supporting lugs or webs B, which strengthen the bearing. The plate A has its upper face planed true for the reception of the knife 0 The under face of plate E forming an inclined plane with the upper face or knifeseat, it will follow that the action of centrifugal force in tending to throw the knives ofl' will in reality bring them into tighter connection with the bearing-plate E by forcing the head of the T-bolt, by which they are secured thereto, up the inclined plane of its under face; hence the knives will be held on the wheel by a force directly increasing with the rapidity of its revolution. The edges of the knives will, as observed, project through apertures E in the jointing-wheel A.

The operation of my improved jointing-machine is too apparent from the drawings to need further description than to say that the shingles are rested on the table, or rest, while their difierent sides are successively presented to the cutting-action of the knives of the wheel, which latter makes some hundred revolutions per minute.

Having thus described my invention with regard to its mechanical construction and its modus operandi, I will now briefly recite some of the numerous advantages it possesses over the forms of shingle-jointing machines now in use. An advantage of paramount importance lies in the pivotal and reversible adjustment of the shield. By means of the pivotal adjustment I am enabled to raise the shield for the purpose of changing and sharpening the knives, and when this is accomplished to replace it in exactly the same position that before obtained to it. By making the shield reversible, and providing one face of shield with two rests and the other with one, I am enabled to operate it with a force of one or two workmen, as desired. Other advantages will be found in the adjustable socket, by means whereof the shield is always returned to its proper position on the flange-face of the lower casing, in the butting pieces or gage pivotally secured .to table-rests, and in the manner of strengthadjustment.

It is evident that many slight changes in theconstruction and arrangement of parts of my machine may be resorted to without departing from the spirit of my invention, and.

hence I would have it understood that I hold myself at liberty to make any such changes as fairly fall within the scope thereof.

Having fully described my invention, what I claim as new, and desire to secure by Letters ,Patent, is-

1. In a shingle-jointing machine, a shield adapted to be reversed to present either its front or rear face to the front face of the jointingwheel, and having one face provided with one and the opposite face with two apertures through which shingles may be presented to the wheel, substantially as set forth.

2. In a shingle-jointing machine, the combination, with a jointing-wheel having cutters projecting from one side thereof, of a pivoted cowl adapted to cover the upper-portion of the jointing-wheel, said pivotedcowl being provided onone side thereof with two shinglefeeding apertures inclined to each other, each of said apertures being furnishedwith a supporting-table, substantially as set forth.

3. In a shingle-jointing machine, a shield having its front and rear'faces respectively provided with one and two devices for supporting shingles while being cut in the jointingwheel, substantially as set forth.

4. In a shingle-jointing machine, the combination, with an adjustable socket consisting in an elongated plate having lateral slots, by means of which it is secured to the wheel-casing, and two vertical arms or lugs, of a shield provided with ears at each end, any one of said ears being adapted to be received between the arms of the plate, and thus hold the shield from lateral movement, substantially as set forth.

5. In a shingle-jointing machine, a shield adapted to be reversed to present either its front or rear face to the front face of the jointing-wheel, one face of the said shield being provided with two tables, and the opposite face thereof with one table, substantiallyas set forth.

6. In a shingle-jointing machine, the combination, witha jointing-wheel having cutters projecting from one side thereof, of a pivoted cowl adapted to cover the upper portion of the jointing-wheel, shingle-feeding apertures (one or more) located in both sides of the pivoted cowl, and supporting-tables provided with adjustable end pieces located at the under side of said feeding apertures, substantially as set forth.

' In testimony that I claim the foregoing I have hereunto set my hand.
